TO ALL WHOM 'IT MAY CONCERN: Be ,itknownf that I, GEORGEBUCKL, of Detroit, in the county of Waync, and State of Michigan, have invented a. new and improved Plane; and I do hereby declare that the following is :t full, clear, and exact description thereof, which will enable those skilled in the artto make and use the same, reference beinghad to the accompanying drawings, forming p'art of this specification.

f llhe object of, this invention is to provide a plane so arranged that the cut may be regulated either in a positive mann-er or by the pressure of the hand, and that thel bit may be roised out of contact with the board being operated on when it is being moved back.

It consists in making the stock in two parts, one part, which supports the bit, being pivoted at the rear'end in a longitudinal channel through the other, and provided with a spring and adjusting-screw at the other end,

the springs being so arranged as to throwthe bit ont of Contact with the board when the pressure of the hand is removed, and the set-screw governs the amount of such movement.

Figure 1 represents a longitudinal sectional elevationl of my improved planefand Figure 2 represents a transversesection on theline a: :z: of iig'. 1.

Similar letters of reference indicate corresponding parts.

A represents one part of the stock, which is provided with a deep and wide channel in the upper portion from end .to end, as clearly shown in iig. 2, and withan opening through the bottom for the plane-bit, shown at B.

C represents theother part of the stock, which is itted to the channel in the part A, and pivoted thereto at the rear end, vas shown at D.

It is provided with the usual opening for the plaine-bit and wedge, and for the escape of the shavings, and at the fro'nt end with a spring, E, in arrecess in the un'der face of the same. The said spring bears upon the bottom of the channel, and has a constant tendency to raise the part C away from the said bottom of the channel.

F represents a set-screw, which screws into a nut in the bottom of the channelV in the part A, and arrests "the upward movement of the part C, due tothe action of thespring. The said screw may be adjusted to regu late the said'movement ofthe part C, as desired.

'The plane-bit boing set by the wedge in the part C as desired, the operator, in using the plane, may, on-

shoving it'i'orward, so press down the front end of the part C as to cause the bit -to take the full cutfor which' it isset, or, by a lighter pressure, take but a. part of the said cut, and when the cut has been made, and tbe pressure necessary for making the same is relaxed, the spring will throw the part C up so as to take the edge of the bit out of contact with the surface being planed while the plane is being` drawn back, thereby protecting the edge from being worn round from that cause.

I claim as new, and desire to secure by Letters Patent- A plane-stock, constructed ofthe parts A and C, pvoted together, and provided with a spring, E, and setsercw, I", substantially as and for the purpose s`et forth.

The above specification of my invention signed by me, thiseighth day of July, 1868'. l GEORGE BUCKEL.
